To all whom it may concern:

Be it known that we, JOHN R. MONTGOM- ERY and GEORGE M. MONTGOMERY, citizens of the United States, and residents of Windsor Looks, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Smoothing Material, of which the following is a specification.

This invention relates to an improved smoothing material which may be made in difierent degrees of fineness for the purpose of smoothing and finishing roughened surfaces, removing paint, varnish, etc., and used in a way similar to that in which what is commonly known as sandpaper or emery cloth is used.

The object'of the invention is to produce a material of this general nature which will be very efficient and quite indestructible.

In the drawingsFigure 1 indicates gen erally a mass of the material as it is ready Fig. 2 shows on enlarged scale a piece of composite strand. Fig. 3 shows on enlarged scale a piece of compound strand. Fig. 4: shows on enlarged scale a piece of compound strand of a coarser grade than that shown in Fig. 3.

The material forming the subject matter of this invention comprises a pliable core of cotton or other pliable fiber upon which is wound a very fine ribbon of metal, such for instance as steel or copper, this ribbon being flattened out to such a degree that its edges are fairly sharp. This metallic ribbon is wound spirally onto the cotton core more or less tightly, as will be best adapted to the particular fineness of the material being made, and as the composite strand is completed a sufiicient amount of it is thrown loosely and allowed to kink and snarl naturally owing to the twist of the core, so that it produces a tangled snarled-bunch of material of a size for instance which will fill the palm of the hand. The pliable core supports the metallic ribbon and prevents its being bent so sharply as to cause it to break and splinter off, and the snarling fproduced by the natural untwisting action 0 the core has a tendency to throw the edge f-the me- .tallic ribbon out slightly causing it to besired two ofthe composite strands may be twisted together to form what I term a compound strand. The twisting together of the two composite strands, and then the normal untwisting tendency of the core, cause the metallic ribbon to stand out from the core, presenting very effective cutting and smoothing edges. If the mass of the material being used becomes filled with dust or dirt, it can all be readily shaken out, and the mass always maintained in a clean and efficient condition. It can be used with the bare hand without any danger of splinters being driven into the flesh, and since the material is very'pliable, and in its kinkedup or snarled condition provides an infinite number of worlnng edges, it will readily follow uneven surfaces and produce a uniform and even finish on the work.

Where non-corroding metals, such as copper, are used for the ribbon, the material becomes an effective household utensil,

ordinary conditions of use its life is almost alimitiess. particularly as compared with the life of the above mentioned articles.

We claim as our invention:

1. A material of the character described, comprising a pliable core and a metallic ribbon wound about said core.

2. A material of the character described, comprising a pliable core and a metallic ribbon wound about said core, the resulting from a composite strand comprising a pli- 13 strand being formed into a, loose tangled able core and a, flexible fiat metallic ribbon massA 1 1 h d b d wound about said core.

3. materia of tie c aracter escri e comprising a pliable core and a flat metallid ribbon having a sharp edge wound spirally about said core. Witnesses:
